The figure shows a semi-circular wire of radius 10 cm in the xy plane carrying current 2 A. If the magnetic field in the region is 3.0 T(-k) then the magnetic force on the wire will be

The figure shows a wire frame in xy-plane carryigna current I . The magnetic field at the point O is

The figure shows a wire frame in xy-plane carryigna current I . The magnetic field at the point O is

An 8 cm long wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. If the magnetic field inside the solenoid is 0.3 T, then magnetic force on the wire is

An 8 cm long wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. If the magnetic field inside the solenoid is 0.3 T, then magnetic force on the wire is

A semicircule wire of radius R and carrying a current I si placed in the XY plane where the uniform magnetic field is B = B_(0) K . The force on the wire is

At a distance of 10 cm from a long straight wire carrying current, the magnetic field is 0.04 T . At the distance of 40 cm , the magnetic field will be

A straight wire carrying a current of 12 A is bent into a semi-circular are of radius of 2.0 cm as shown in the adjoining figure (a). Consider the magnetic field B at the centre of the arc. Would your answer be different if the wire were bent into a semi-circular arc of the same radius but in the opposite way a shown in figure (b)?
